himself. The medicament may be of a nasty or sal'vey consistency and maybe introduced l f' Vnient shown in Fig. 3 may be adopted. In

between the plunger of piston 14 and the end of the plug 17.

In the modification illustrated in Fig. 2 I have shown the same piston 14, stem 15 and spring 16 but the plug 1711 is of simpler construction, the button or other catch being omitted. The-medicament is, as before, inserted at 2O between the plug and piston 4and in this case must necessarily be of greater consistency than before inasmuch as it must withstand the pressure of spring 16 during the application of the instrument. A material such ascocoa butter is frequently used in this` instrument as a base for the medicament, the same being provided in the form of a cylindrical, axially bored cake which will become softened by the body temperature so as to become expressed through the ducts 11; though other bases could obviously be employed.y i

v In case it be desired to applythe medicalmcnt to'a more interior portion the' arrange- "this embodiment a plunger 14u is employed and the stem l'L and spring lare located upon the same side thereof. Ifh'e' threaded end 13 of the chamber is provided with a .plug 171 having an axial borefor. the reception of the stem'. This bore. asl before, merges with a recess 21 but this recess is provided with a. spring catch -22 and the stern 15a is provided with a head 23 adapted to engage this catch and be retained thereby against the force of the spring 16u. In the present embodiment the catch 22 consists of a V-sbaped spring havingfin one of its sides an aperture adaptedto receive the head 23.

The medicament is inserted into the end of the chamber ras shown at 31.

In case it is desired 4to employ this device f' for the giving ofy enem'as the plug 17 is replacediby a. tube connection 25` the same l;a\ ing at its outerend a nipple 26 adapted fmwhc attachment of a suitable conduit 27 fand preferablyhavingits inner end extended as at 28 so'as to cover up the ducts 11 and prevent the escape of liquid therethrough.

Thus when the button is turned as shown in Fg. 1 the piston 11i-.is prevented from advancing and the It will be obvious that this instrument could be made in a large number of different sizes and diameters and With different designs While still retaining the important and desirable features hereinbefore pointed out. It will therefore be understood that the attached claims are intended to extend to and include all such modifications and variations of the said device so far as the same fallr Within .the sco-pe of my inventive idea.

Having thus described my invention, What I claim is 1. Ina device of the character described the combination with a cannula having an interior cylindrical chamber extending fro-m its oase to apoint adjacent -to the tip thereof, the wall of said cannula being formed adjacent to said base with a plurality of ducts communicating with said chamber, of 1 2.

adapted for insertion into theouter end of said chamber and having a bore adapted to receive said stem, the space between said plug and plunger when the latter is repelled serving to receive medicament.

3. In a device of the character described the combination With a cannula` having an interior cylindrical chamber extending from its base to a point adjacent to the tip thereof, the Wall 'of said cannula being formed adjacent to said base with a plurality of ducts communicating With said chamber, of a slidable plunger for said chamber, a stem carried by said plunger and projecting froml its forwardside, a compression spring carried by the opposite side of said plunger and arranged tobe co-mpressed against the inner end of said chamber, a plug adapted for insertion into the outer end of said chamber and having a boreadapted to receive fsaid stem, and a manually releasable catch car-v ried by said plug and adapted to engage said stem and prevent the advanceof said plunger until displaced, there being a space iso 1 `living to receive medica# ith `acannula having an chamber `extending from said "with sa "plurality of nicatingwith said chamber, yof luragerIk for saidlchamber, a com;- rfing adaptedto Hbe interposed bet ldf vpluiigert" and tlieinner` end of nibell in 1is"fr-1closing the outer `ducts commu new@ infcoiinectionywith" said closing means a Imedicameli I frec-eivingspace, and displaeeblew plungervagainst "ed r cmg: movement.
